separate from the shoe.

Another object is to provide a device of this nature with suitable "invisible'securing means for firmly holding the device in place.

Another object is to suitably form the device so as to closely simulate thewelt of a shoe.

Another object is to produce a device 01": this nature which shall be simple ofconstruction, cheap to manufacture, and highly efiicient for the purpose for which it is designed.

With these and other objects in View as will be more apparent, the invention consists in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claim, and are illustrated in the accompanying drawing, in which Figure 1-is-a top plan view showing the device as extended in the act of placing the same on a shoe. I

Figure 3is a bottom plan View. f Like characters of reference refer to like parts in'all views. J

The present invention contemplates the construction of a rubber covering for the soles of shoes which shall grip the shoe by its inherent resiliency-and which shall be suitably secured to the shoe by substantially 1 am aware that there have been various attempts to attain similar ends, but in'these .prio'r devices, there has been incorporated a layer of fabric or metal which entirely did away with the, elastic effect of the rubber coating, and the securing devices have'been such 'as stand away from the body of the shoe and either form an obstruction; to the free use of the foot or else show in an unsightly manner.

Bejerring to the drawing in detail, 10

represents the body of my improved rubber covering for shoe soles, which is formed with an upstanding and inwardly projecting "flange 11 which extends fromthe instep around the toe to the other side of the .instep. This flange 11 is provided upon its;

upper surface with a plurality of extrusions or lugs 12 which are arranged so as to give the impression of the stitching of the welt.

' The entire shoe body and flange is made of flexible and elasticrubber material so that it will stretch out to the position shown in Figure 1 in applying the device to the shoe.

After the flange 11 is brought into close; contact over the top of the welt, it is then necessarythat the device be secured to the shoe. This securing means which I provide consists of a screw and a plate. At the ball of the foot, I insert a short screw/"14 which holds the forward part of the device in place. At the instep the flangell fades into the flat thin sole part which is extended u into the instep at 15. Across the end of this plain thin portion 15,1 place a bar 16 which I secure to the shoe with: three screws 17."

Adjacent the centre of the bar the thick part of the sole merges intoa pointed portion to strengthen the centre of the sole, and from this pointed portion the sole proper curves laterally and partially fbrward, and from the curved portions the sole merges into the flat thin sole part, which lies under the bar,- and is thereby secured. Since the bar has its centre immediately adjacent the pointed portion the sole isheld more secure and strengthened at such point." In this manher, it will be seen that I have provided a positive securing means which is practically invisible and which oifers nothing to catch and tripthe wearer.

' While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the parts may be varied without in any way do arting 'from the spirit of my invention, and I fore do not limit myself to the exact details of construction herein shown nor to anythin less than the whole of my invention limi only by the appended claim.

What I claim is v I An attachment for shoe soles comprisin a relatively thick rubber sole provided wit an upstanding marginal flange about the major ortion. of said sole, exceptin the termina of said upstanding marginal ange which terminate a substantial distance from where the sole lies. adjacent the inste whereby the side portions of the rubber so e may be flexed to permit easy removal of the rubber sole, said flange adapted-Ito engage with and overlie the marginal edge of a shoe 1 theresole, said rubber sole at a point immediately adjacent the forward part of the instep mergin into a relatively thick pointed portion, w ich strengthens the, centre of the rubber sole, said rubber sole on opposite sides of the pointed portion being curved laterally and artially orward, and from the curved portions the sole fades into a flat thin sole part engaging with the forward-part of the instep, a, perforated transverse bar engagingshank of the shoe sole, to secure the parts to ether.

testimony whereof, I aflix my signature CIRIACHINO FURCOLO.
